PHOTOGRAPHIO STAND.

SPECIFCATION forming part of Letters Patent No. 693,792, dated February 18, 1902.

Application filed April 16,

T0 a/ZZ whom, nm/wy concern;

Be it known that I, HARRY DENMAN FAR- QUHAR, a citizen of the United States, and a resident of Brooklyn, in the county of Kings and State of New York, (having my postoffice address No. 693 Quincy street, Brook' lyn, New York,) have invented certain Im"- provements in Photographic Stands, of which the following is a specification,v reference being had to the accompanying drawings, in which- Figure l illustrates a side elevation of the apparatus, parts being shown in section. Fig. 2 illustrates a rear view of the apparatus, the vertical slideway being removed for the salie of clear-ness in the drawings.

In process printing as practiced prior to my invention the subject has been mounted upon a frame supported upon the stand or elsearranged upon the wall or otherwise supported in line with the axis of the lens Of the camera. In using apparatus thus'arranged it is fre quently a difficult matter to support or hold the subject in proper position owing to the Vertical (or at least substantially Vertical) position it must assume in order to be properly located relative to the lens and also in suitable position for the purpose of focusing. It frequently happens that the subject can be set up, arranged, or supported in proper position onlyV at considerable trouble, and

sometimes by such means as interfere with the perfection of the picture or print, and sometimes if the arrangement is found unsatisfactory it hasto be done all over again.

The purpose of this invention, therefore, is to overcome the above-stated objection by a simple and relatively inexpensive apparatus which embodies a prism or its equivalent, an inclined mirror, suitably located relative to the lens-tube, and a suitable frame added to the apparatus as constructed prior to my invention, which frame has an adjustable table or ledge upon it adapted to support the subjects to be photographed, whereby they may be adjusted relative to the lens and for focusing purposes. Since under my invention the support is horizontal, no devices are necessary for holding the subjects to be photographed in their desired position, because 1901. Serial No. 56.045.

they may be placed in any position desired and will be held therein by the action of gravity only, and if a change in the position or location of a subject be desired -it can be effected in a moment and at no expense or trouble.

In the drawings, A represents the base or support for thestructure, which is preferably provided with casters B.

C is an upright frame, preferably composed Of two uprights, one on each side of the apparatus, which may beneiciallyvbe somewhat longer than those employed: in the old form of such apparatus.

D D are trunnions at the upper ends of the uprights C.

. E is a horizontal and tiltable table or based board pivoted on the trunnions D, and Fis a brace 0r stay for the table, which may be heldin any desired position by the clampingwheel G.

H represents springs having slide-blocks I,

lone of them provided with a set-bolt J, the

blocks sliding in a slideway K, made on the lower edge of the frame L, which carries the camera M.

N isthe lens-tube of the camera.

All of the parts thus far described are or may be ofthe usual form.

It will be understood, of course, that suitable cross pieces or bracesl are employed `to connect and stiffen the two sides of thefseveral parts referred to, one side only being shown in the drawings, since it is an elevation of the apparatus.

Referring now to the parts more immediately concerned in my invention, O is a prism or, as illustrated, its equivalent, an inclined mirror, the construction of which is now too well-known to require' detailed explanation. It may be attached to thecamera in any suitable manner. I show it as arranged upon the lens-tube. It may be threaded thereon or fastened by a clamping-ring or otherwise supported, as preferred.

P P are two downwardly-extending side pieces which are bolted to the forward ends of the frame L of the apparatus and depend therefrom toward the floor.k They are suit- IOO on their inner edges they have each a slideway R, in which slides the edges of a crosspiece S, Which forms the rear part of a table T. The table is preferably braced by a bracket U, connecting with the cross-piece S.

At the central rear portion `of the crosspiece S there is a nut V, fastened in any suitable manner, in which screws athreaded rod W. This rod has a beveled pinion a at its upper end, which gears into another beveled pinion b, which is mounted upon a horizontal shaft c, Which in turn has a beveled pinion d on its rear end, which engages With a corresponding beveled pinion on a cross-shaft e, this shaft being actuated by a hand-Wheel f, which is so located as to be convenient to the hand of the operator. The several shafts are of course suitably journaled in bearings on an appropriate part of the apparatus.

The operation is as follows: The apparatus asa whole is movable on the casters B, asv

usual, and the angle of the camera is regulated, as usual, by tilting the base E, which in turn adjusts all the superposed structure as may be desired. The springs H relieve the apparatus of shock or jar, and the upper frame L, which immediately supports the camera, may be shifted to the front or rear, sliding upon the springs, by slacking the setbolt J, whereupon the blocks I may slide through slideways K, as usual. The subjects to be photographed are placed upon the table T, which obviously may be covered with such material as Will best throw up the subjects, and the adjustment of the subject relative to the lens for the purpose of focusing, dac., may be made exact by turning the hand-Wheel fin such manner as to elevate the table T or depress the same by the appropriate rotation of the threaded rod WV. The light may be made to fall upon the subjects at such angle as desired by the proper horizontal tilting of the apparatus and by turning it upon its casters, so as to present the apparatus, and consequently the subjects, to the light at such angle as preferred. The operation of the mirror or prism is of course Well understood. The reection from the subjects lying upon the table T will be received upon it and thus deflected through the lens and the picture taken upon the sensitized surface at the focal plane.

It will be obvious to those who are familiar with this art that modifications may be made eesfrea suitably-supported and tiltable base-board, a

frame for sustaining the camera, spring-supported on the base-board, a slideWay rigidly connected to said frame at approximately right angles-thereto, and an adjustable table on said slideway.

3. A photographic apparatus embodying a horizontally-exteuding and suitably-supported base-board, springs supported on opposite edges of the base-board, a frame for sustaining the camera supported on said springs, a slideway rigidly connected to the said frame at approximately right angles thereto, a table vertically adjustable in said slideway, and means accessible to the hands of the operator for adjusting said table.

4. A photographic apparatus embodying a s-uitablysupported and adjustable baseboard, a frame for sustaining the camera, spring-supported on said base-board and longitudinally adjustable on said springs, a slide- Way rigidly connected to said frame at approximately right angles thereto, and an adj ustable table on said slideway.

5. A photographic apparatus embodying a frame for sustaining the camera, springs for the support of said frame, means to adjust the frame on the springs, a slideway rigidly connected to said frame at approximately right angles thereto, and a table supported by and adjustable in said slideway.
